Ashlee Simpson's representative has moved swiftly to dismiss reports the singer's marriage to Pete Wentz is in trouble, insisting the couple is still "in love".

Ashlee Simpson, who married the Fall Out Boy rocker in 2008, was said to have been jealous of her husband's relationship with his bandmate Bebe Rexha, who fronts his new act, Black Cards.

But a spokesperson has branded the story "completely inaccurate", telling GossipCop.com, "Ashlee is happy writing songs and she is incredibly supportive of Pete, as he is of her. They're in love and remain committed to one another and their son."
